Markdown class

A component that renders markdown to ANSI-styled terminal output.

Automatically adapts syntax highlighting and styles based on terminal background (dark vs light) using RenderConfig.

// Basic usage
final md = Markdown('# Hello\n\nThis is **bold** text.');
print(md.render());

// With RenderConfig for theme adaptation
final config = RenderConfig(
  terminalWidth: 100,
  hasDarkBackground: false, // Light terminal
);
final md = Markdown(
  '```dart\nvoid main() {}\n```',
  renderConfig: config,
);
print(md.render());

// With custom options
final md = Markdown(
  markdown,
  options: MarkdownOptions(
    syntaxTheme: AdaptiveChromaTheme.draculaGithub,
    tableBorder: Border.rounded,
  ),
);
